My invention relates to control devices and more particularly tomechanism for controlling: the operation of automatic talking machines",the said-controlling mechanism being placed at a distance from theoperating mechanism for the talking machines.

It is an object of the invention to provide a control device of thischaracter in which the cabinet containing the records and the operatin gmechanism may be located in one'place and a soundprodi'icing unithaving-associated therewith control mechanism may be positionedinanother place.

The invention is an'impr'oveme-nt over the machine shown and describedin my copendirrg a plication, Serial No; 1683674, filed Februa ry 16;1927, for automatic talking machines. The improvement consistslll'plOVlfiling'the talking machine presentedin said'applicat'ion withareproducingiunit which may be positioned at a distance from the 1cabinet containing the records and thebperating .7 mechanism for playingthem anc. providing means for controlling the operating mechanism at ornear the reproducing unit.

The mechanism for rotating the record table for changing records is thesame as-that shown in the application above referred to. This invention;however, is provided with aae'lectrical pick-up which transmits impulsesto anau'iplifi cr from which they are transmitted to a loud s'peakingunit and reproduced in a manner well known to -tli'e n'iusicalworld.

Referring to the accompanying drawings which are made apart hereof andon which similar reference characters indicate similar parts;

current.

Referring now to Fig. 5, wherein is shown a diagrammatic view of'thewiring constituting the controlmechanism and the operating mechanism ofthe cabinet, numeral 16 indicates a record table for supporting therecord to be played and 17 the tone arm carrying a tone box 18. The tonebox in this application is in the nature of atelephone transmitting unitfor transmitting impulses through wires 19' and 20 to an amplifying unit21. lVires 22 and 23 lead from the amplifying unit to a loud speakerunit at in the loud speaker 12. A resistance element 25 is connectedacross the wires 22 and 23 to provide a volume control for the loudspeaker.

Since the method oi transmitting sound waves and reproducing them at adistance by means of a loud speaker is well known "further descriptionis believed uimeccssary.

The mechanism for changing records and for setting in motion the recordchanging mechanism is the same as that shown and described in theapplication above referred to and will be described here only insuiiicient outline to furnish an understanding of the control mechanismrepresenting the subject matter of-this application.

Numeral 26 indicates the motor for driving the record changing mechanismon the phonograph. This motor is operated by currenttaken from wires 27'and 28 connectedlo suitable source of current as, for example lead inwires 29 and 30. lVire 31 connects the wire 28 through switch elements32 and 33. These switches are normally open but when either one or bothis closed current is fed to the motor 26 to operate the record changingmechanism; The switch 32 is operated by the tone arm 17 as it swingsinto the center of I the record upon completion of the playing Y of therecord. Since the switch 32 is closed only for a short time switch 33 isclosedby suitable mechanism to continue operation of the record changingmechanism until the record has been, changed and the whole machinerestored record. 1 /Vires 34 and '35 connect wires 31 and 28 at 36 and37 respectively. Wires 34 and 3 5 lead to a switch 38 on-th'e controlmechanism 13. This switch-38 is normally open. it

ymay be closed, however, to provide means 'ing the record. .othcr sideof this motor. A wire 50 is conind ependent of the tone arm for.operating the record changing mechanism as shown and described in thecopendin-g application referred to. A wire 39 connected to lead in-wire29 at'40 leads to a point 41 on a double throw switch having forks 43and 44. Wire45 is connected at 46 to an arm47 with which the fork 44 onthe double. throw switch makes contact in oneof its positions. The wire45 also connects to one side of a motor 48 at 49.

This motor rotates the record table for play- The wire 28 connects thearm 62 with which the fork 43 of the double throw switch makes contactin" one of "its positions. Awire 63 isjoined to wire 66 at 64 and leadsto a post 65 on a switch element 66. A wire 67 connected to post 46joins the switch element 68 at 69. The contact points 96 on the members66 and 68 are normally in contact during the playing of'a record.

The switch 56 is normally open. This switch, however, is closedmomentarily with each change of a record to energize the solenoid 59 fora purpose which will later appear. A circuit breaker 7.1 may bepositioned in th line 27 to interrupt the current to the motor in casethe record changing mechanism should become jammed. For operating thiscircuit breaker, I preferably use the device shown in my copendingapplication, Serial No. 218,301, filed September 8, 1927, for automaticcircuit breakers. 1

As shown in Figs. 3 and 4, a ratchet wheel 7 2 provides means forplaying continuously a predetermined number of'records. In theapplication above referred to this ratchet wheel or escapement means isoperated by movement of therecord table. In the invention hereinpresented I operate this escape ment mechanism by the solenoid 59 which,as i above stated, isenergized at the end of each record that is played.The solenoid 59 pulls to position to play the next down on the arm 7 3which-allows a spring to rotate the escapement mechanism through onenotch A manually operated handle 7 4 is pivoted in the front plate ofthe control mechanism and has an arm adapted to engage the escapementpawl 3. Oscillation of thepin 74 will release the pawl 73 sons to allowrotation ofthe escapeinent wheel. This provides means for manuallyrotating the escapementwheel.

Pivoted in the front plate of the control j mechanism 1s a lever 7 6having a roller 77 of insulating material. This roller engages the outercurved ends of the members 43 and 44 on the switch 42. As shown in Fig.3, the lever 76 is in the neutral position. "When the lever 7 6 isturned to theright, the roller 7 7 will press against arm 44 and makecontact with the arm'47. When the lever is moved to the'left. contactwill be made be- I records in the cabinet of the machine.

When the lever 7 6 is turned to the right, so as to make contact betweenmembers 44 and 47, current may pass from the lead in wire '29 throughthe wire 39 to contact point 41, through arm 44, arm '47,.thr0ugh wires45 and 50 to the motor which operates the record table and to theamplifier respectively. It is immaterial whether the switch points 90are in contact or not since the current does not have to pass throughthem. When, however, the lever 76 is moved to the left, current passesfrom lead in 29 through wire 39 to contact point 41, through arm 43, arm62, through wire 63, through switch arms 66 and 68, through contactpoints 90, through wires 67 and through wires45 and 50 to the motor '48and amplifier 21 to rotate the record table ing mechanism is positionedin some remote placeout of the way.

electrical pick-up is well known. The record changing mechanism and theautomatic movementsof the tone arm and the record table which causeoperation of the record changing motor are shown and described in theapplication above referred to and form no part of this application. Butin this application the means for controlling the operation of thesedevices are placed on the control unit 13. As shown, these controllingdevices consist of lever 7 6 which when in neutral position will holdthe operating mechanism in inoperative position but when moved either tothe right or to the left will cause continuous playing of the records onthe machine or will play a predetermined number of records. The plunger7 8 provides means for rejectingany record before it has been completelyplayed. The knob 79 provides volume control for the loud speaker.

It will be seen, therefore, that I have provided means remotelypositioned from the record cabinet and the operating mechanism forcont-rolling the playing of the records.

Theloud speaker unit and the control unit may be housed in an attractivesmall cabinet which may be placed on a desk, or mantel, or a table, ormay be readily moved from place to place with ease.

It will be obvious to those skilled in the 'art that various changes maybe made in my device without departing from the spirit of the invention,and I, therefore, do not limit myself to what is shown in the drawingsand described in the specification, but only as set forth in theappended claims.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent, is:

1. A talking machine comprising two units, one comprising a cabinetcontaining the records and operating mechanism therefor including anelectric pick-up device and an amplifier, and the other adapted tocontain a speaking unit and mechanism for controlling the operatingmechanism in the firstnamed cabinet, the unit containing the speakingand the controlling mechanism being positioned remotely from theoperating mechanism, substantially as set forth.

2.
